Hardness Testing Fixture Block
A hardened steel V-block fixture engineered to hold metal test specimens securely during Rockwell, Brinell, and Vickers hardness testing. The precision-ground V-groove accommodates round and flat specimens, while the screw-operated clamping mechanism ensures the workpiece stays immobile under indenter load—critical for accurate, repeatable hardness readings.
Product Overview
In hardness testing, even microscopic specimen movement can skew readings and damage indenters. This fixture block addresses that problem with a rigid V-block design that seats the specimen firmly, combined with a screw-driven clamp that applies controlled holding force without deforming soft materials. The hardened steel construction withstands repeated clamping cycles and indenter proximity without surface degradation.

Key Features
- Hardened steel V-block with 90-degree precision-ground groove for stable specimen seating
- Screw-operated clamping with knurled knobs for controlled, repeatable holding force
- Versatile specimen accommodation — holds both round bars and flat plates up to 50 mm
- Ground surface finish (Ra 0.8 micrometer) prevents marring of test surfaces
- Bench-mountable with threaded holes for rigid fixture on any test platform
Product Advantages
- Reading accuracy: Secure clamping eliminates specimen shift that causes false readings and indenter damage
- Durability: HRC 55-60 hardened steel resists wear and deformation through thousands of test cycles
- Adaptability: Single fixture handles multiple specimen geometries without accessory changes
- Operator efficiency: Quick-load clamping reduces setup time between consecutive tests
Applications
- Quality control labs performing incoming material hardness verification
- Heat-treatment shops validating case depth and surface hardness
- Metallurgical laboratories conducting routine hardness surveys
- Production lines requiring 100% hardness checking of critical components
